If AIR BAG warning light does not flash 7 times and go off, inspect vehicle for signs of damage or addition of aftermarket devices which could affect operation of AIR BAG warning light. If visual inspection is okay, go to AIR BAG WARNING LIGHT CIRCUIT MALFUNCTION .
- Connect scan tool to Data Link Connector (DLC), located under left side of instrument panel. Turn ignition on. If scan tool powers up, go to next step. If scan tool does not power up, inspect and repair data link communications circuits.
- If scan tool communicates with SDM, go to next step. If scan tool does not communicate with SDM, inspect and repair data link communications circuits.
- Request SIR DTC display. If scan tool displays DTC's, go to next step. If scan tool does not display DTC's, SIR system is okay.
- If scan tool displays DTC's that begin with "U", inspect and repair data link communications circuits. If other DTC's are displayed, perform appropriate diagnostic tests. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table.
